Royal Oak Extra-Thin Openworked 39mm

How it wears

Wears larger than its 39 mm case suggests

Audemars Piguet Royal Oak Extra-Thin Openworked 39mm measures 48.5 mm lug-to-lug on a 39 mm case, a lug-to-lug ratio of 1.24 against a database median of 1.18. That span is longer than 70% of the 7,421 watches in this database and longer than 16% of the 68 Audemars Piguet watches listed.

A flat wrist width of 54 mm (2.13 in) or more keeps it in the balanced range, and from 65 mm (2.56 in) it starts to look compact. Below 48.5 mm (1.91 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.
